I had one like that when dd#2 was little. It was ok, but sometimes my boob would stick out the slit if I wore it during the day, and I prefer a wrap top or top slit...
I think I might try making an 18th century shift and doing what I read they used to do-slitting the front down and binding the edges and adding a tie...
Good thing I have pinking shears!
I don't have jersey, either, so the wrap front won't work, nor will that pattern.
